yTo all whom it may concern.'

Be it known that Lfltuinoo M. Monoraii son, a citizenof the United States, residing yat Winston Salenni'n the county of Forsyth and Stateof North Carolina, have invented certain new and useful rimprovements in Cary Seat-Operating Devices, of whichk the folyproved shifting or reversing device;

lowinv' is a s aecification reference beinO had n p f f r,to the accompanyingdrawings.

` This invention relatesto improvements in carfseats'and more particularly devices for simultaneously reversing a'plurality of car seats such as set forth .in my pending application for patent filed-October 12, 1907 and bearing Serial Number 397,181.

The object of the present invention is to rprovide a `simple and y rpractical means for simultaneously shifting or reversing a plural-` ity of seats and locking them in either position after being shifted.

With theabove and other objects in view, the rinvention consists ,of the novel features of construction andthe combination and arrangement ofparts hereinafter fully describedandv claimed, andillustrated in the accompanying drawings, in which Figurel fis a vertical section through a plurality of car seats rillustrating the iin- Fig. 2 is an enlarged or detailview of the device for operating and locking the reversing bar;

- and Fig. 3 is asection taken on the plane inthe cross :i dicated bythe line 3-3 in Fig. 2.

v In the drawings 1 have illustrated the car seats set forth in my co-pending application abovenientioned, the 'same being arranged along each side ofa` caror coach and each comprising a suitable frame 1 having upright posts 2, side bars 3 and cross bars 4.

6 denotes afshiftable seat bottom carrying bifurcated metal plates `28 which straddle portion or 'connecting bar 15 of a U-shaped hanger 13,.- the arms 14 of which i arepivoted,intermediate their ends, as at 18,

upon'the bars4. A reversible seat back l2 is pivoted ybetween the arms 14 of the hanger Q13 and rits lower* end is guided by a guide plate secured between the rposts, or legs 2.

denotesja double footprest hung from the cross kbar 15 of the U-shaped hanger 13 and adapted to be reversed simultaneously with the seat ,6 and back 12 `when the hanger l is shifted, as will be understood upon reference to Fig; 1, in which the said parts are shownin full linesin one position and in their reversed positionin dotted lines.

" i Application filed December 5, 1908. Serial No. 466,136.

84 denotes a reversing bar for simultaneously reversing all or a plurality of the seats upon one side of the car. Said bar is slidably mounted in suitable guides upon the posts 2 and it carries pins 35 which work in longitudinal slots 38 in the arms 14 of the hanger 13. At one end of said bar upon its bottom edge is formed a rack 39 which meshes with a gear 40 fixed to a shaft 41 formed integral with a disk 41a which is rotatable in a bearing bracket 40b suitably secured to the wall of the car or to any other support. The projecting or outer end of the shaft 41 is squared., as at 42, to receive a removable crank handle 43 by means of which said gear may be rotated to shift the bar 34 in either direction for the purpose of reversing the seats connected to it by the slot and pin connections above referred to.

For the purpose of locking the bar 34 against movement and thereby locking the seatsin their adjusted positions, I provide the pinion or gear with an annular series of seats or openings 44 any one of which is adapted to receive the angular end of a locking dog 45 pivoted at its other end upon a pin 46 in a bifurcated bracket 47 secured to the car wall or other support. The pivoted end of the dog is formed with fiat faces 48 adapted to be engaged by a spring 49 arranged in the bracket,` as shown in Fig. 3, said spring serving to hold the dog in either its lowered operative position shown in full lines in said figure or its elevated inoperative position shown in dotted lines.

For the purpose of maintaining the rack 39 in mesh with its gear 40 an anti-friction roller 50 is journaled upon a post or stud 51 which projects from the bracket 47, said roller being arranged to engage the upper edgev of the bar 84 Opposite the rack teeth 39.

Having thus described the invention what is claimed is:

l. The combination of a plurality of car seats having reversible backs, arms or levers for operating each of said backs, a longitudinally slidable reversing bar, operative'connections between said bar and said arms or levers, a rack upon one end of said bar, a gear in mesh with said rack and formed in its outer side face with an annular series of seats, means for rotating said gear, a bearing bracket having a bifurcated outer end, a dog pivoted adjacent to one end in the bifurcated portion of said bracket and having at its pivoted end fiat faces and at its free end a right angularly projecting portion to enter any one of the seats in said gear to lock the latter against rotation and a leaf spring secured in the bifurcated portion or end of said bracket and adapted to bear against the flat faces on the pivoted end of the dog to hold the latter either in its operative or inoperative position, substantially as described.

2. The combination of a plurality of car seats having reversible backs, arms or levers for operating each of said backs, a longitudi nally lidable reversing bar, operative connections between said bar and said arms or levers, a rack upon one end of said bar, a shaft having a flat faced outer end and an enlarged circular head at its inner end, a

bearing bracket for said shaft and its enlarged head, a gear fixed upon said shaft and adapted to mesh with said rack, said gear having in its outer face an annular series of seats, a removable crank upon the flat faced outer end of said shaft, and a pivotally mounted, spring pressed dog having an angular free end to enter any one of the seats in said gear to lock the latter against rotation.
